Field notes

The interface separates current 40-man roster players from previous players and offers filters for pre-arbitration, Super Two tracking, arbitration eligibility, and free agency eligibility. Its calculations use 172 credited days per service year, with 3.000 and 6.000 years marking the stated arbitration and free-agency thresholds. The site identifies the MLB Stats API as its source and links both a methodology README and public source code.
